Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a western-style toilet device having a toilet seat on which a human body sits during excretion.

Configuration of Conventional Example and Problems Thereof In general, a Western-style toilet device has a toilet bowl 1 as shown in FIG.
A low tank 2 for storing water for cleaning the toilet bowl 1, a support body 4 fixed to the toilet bowl 1 by a mounting bolt 3, and a rotary shaft 5
The toilet seat 6 and the toilet lid 7 are rotatably attached.

When the toilet lid 7 is used, the toilet lid 7 rotates about the rotation shaft 5 and leans against the low tank 2.
Cover. On the other hand, the toilet seat 6 is placed on the toilet bowl 1 to receive the weight of the human body at the time of stool or female feminine use, but at the time of male feminine use, the toilet seat 6 prevents contamination by small water. Like the toilet lid 7, it is rotated around the rotation shaft 5 and leaned against it. At that time, the toilet seat 6 is leaned against the toilet lid 7 leaning against the low tank 2, but the low tank 7 has various shapes, and when the low tank 7 is largely projected to the toilet seat side, It may not be possible to take a sufficient leaning angle of the toilet seat 6 and it may fall due to its own weight, which not only makes it difficult for men's small use but also hits the user, causing harm and impacting the toilet bowl 1. It was sometimes struck by and damaged.
The toilet seat 6 is often used with a cover,
In that case, the leaning angle of the toilet seat 6 is further reduced,
There was a high possibility of falling, which was a problem. In order to solve this problem, the configuration shown in FIG. 2 has been conventionally used. Second
The figure shows a sanitary washing device for washing the human body part after defecation with the nozzle 8. The hinge part 10 of the toilet seat 9 and the support part 13 connected to the case 11 accommodating the cleaning device and supporting the rotating shaft 12 are shown. A resin-made ring 14 having a wedge-shaped cross section, which is shown in FIGS. 3A and 3B, is provided between the rotary shafts 12 so as to be unrotatable.

When the toilet seat 9 is placed on the toilet bowl 1, the gap between the hinge portion 10 and the support portion 13 is V-shaped as shown in FIG. 4, and the wedge-shaped ring 14 is set in the V-shaped gap. When the toilet seat 9 leans against the pivot shaft 12 as shown in FIG. 5, the clearance between the hinge portion 10 and the support portion 13 changes and becomes narrower than the maximum thickness portion of the wedge-shaped ring 14, and the hinge portion The wedge-shaped ring 14 is compressed in the wall thickness direction by 10 and the support portion 13, and the contact resistance prevents the toilet seat 9 from collapsing by making the rotation of the toilet seat 9 heavy and helping the toilet seat 9 to be independent. ing.

However, in this conventional example, the wedge-shaped ring 14
If the clearance between the support portion 13 and the hinge portion 10 is increased due to variations in assembly, the effect is completely lost and the toilet seat 9 falls down. Cannot be prevented. Even if the dimensions are as specified, even if the wedge seat ring 9, the support portion 13, or the hinge portion 10 is worn out due to a large number of times of opening and closing the toilet seat 9, the toilet seat 9 cannot be prevented from falling down. .

In addition, the wedge ring 14 is exposed to the outside and is unaesthetic in appearance, and cleaning chemicals, etc., adhere to it during cleaning, causing damage or dimensional change due to chemical changes. It wasn't.

An object of the present invention is to solve the above-mentioned conventional problems, and it has a good appearance, and even if the assembly has variations or the toilet seat is opened and closed many times, the toilet seat can be leaned and supported reliably. An object is to provide a highly reliable toilet device.

To achieve the above object, in the toilet device of the present invention, a spring body for controlling the turning torque of a turning shaft interlocking with the toilet seat is provided in a support body in which the toilet seat is rotatably attached. is there.

Description of Embodiments An embodiment of the present invention will be described below with reference to the drawings.

FIG. 6 is an external view showing an embodiment of the toilet device according to the present invention. Reference numeral 15 is a toilet bowl, and 16 is a low tank for storing water for cleaning the toilet bowl 15. A support 17 is provided on the toilet bowl 15 as a first
As shown in the figure, they are fixed by the mounting bolts 3, the toilet seat 18 and the toilet lid 19 are placed on the toilet bowl 15, and the rotating portion 20 is attached.
It is rotatably attached to the support 17 by a and 20b. FIG. 7 is a schematic perspective view showing details of the rotating portion 20a, and FIG. 8 is a sectional view of the rotating portion 20a as seen from the front. Reference numeral 21 denotes a rotating shaft, which is a square hole 23 of a hinge portion 22 protruding from the toilet seat 18 and a round hole 2 of an arm portion 24 of the toilet lid 19.
5 and a circular hole 26 provided on the side surface of the support 17 to allow one end to be formed in the support 17, and a cam 27 is provided at the end thereof, and a retaining ring 28 is used to remove the end. It has been stopped. The toilet lid 19 is free in the direction of rotation with respect to the rotating shaft 21, but the toilet seat 18 and the cam body 27 are not attached to the rotating shaft 2.
It is designed to make the same rotational movement as 1 and therefore
The toilet seat 18 and the cam body 27 have the same rotation angle. Further, below the cam body 27, a spring 31 and a pressure contact plate 32, which are restrained except for vertical movement by a rib 30 extending from the chassis 29 of the support body 17, are provided to press the outer peripheral surface of the cam body 27. There is. 9 and 10 are cross-sectional views of the rotating portion of FIG. 8 viewed from the left side, FIG. 9 shows a state in which the toilet seat 18 is leaned against, and FIG. 10 shows the toilet seat 18 on the toilet bowl. Shows the state of falling. The shape of the cam body 27 is such that when the toilet seat 18 is leaned at a right angle, the dimension a from the center of the cam body 27 to the point A where it contacts the pressure contact plate 32 is larger than at other positions, and the load of the spring 31 is increased. I am supposed to receive it. With this configuration, when the toilet seat 18 is leaned against the toilet seat 18 from the state of being mounted on the toilet bowl, the cam body 2
7 rotates with the toilet seat 18, the load of the spring increases, and the rotating torque becomes maximum in the vicinity where the toilet seat 18 is substantially perpendicular to the toilet bowl. When the toilet seat 18 further rotates from the position perpendicular to the toilet bowl, the rotation torque becomes smaller, and the toilet seat 18
Receives a turning force on the side of the stool lid 19 which is leaned against.

That is, when the toilet seat 18 leans against the right angle when the seat seat 18 leans against the toilet seat 18, the toilet seat 18 will not fall toward the toilet bowl. Therefore, even if the low tank 16 is largely overhanging the toilet bowl 15, the toilet seat 18 can stand on its own as long as the toilet seat 18 is upright. In addition, in this configuration, since the rotational torque is braked by the action of the cam body 27 and the spring 31, variations during assembly occur and the frequency of raising and lowering the toilet seat 18 increases, and the point of the cam body 27 increases. Even if A is slightly worn, it does not have a great influence on the torque braking, and it always helps the seat 18 to stand on its own, which is very reliable. Further, since the cam body 27, the spring 31 and the pressure contact plate 32 are provided in the support body 17, the appearance is good, and further, it is not damaged by a cleaning agent applied at the time of cleaning. In addition, as shown in FIG. 10, the cam body 27 has a dimension b from the center of the cam body to the point B where it comes into contact with the press contact plate 32 when the toilet seat 18 is laid down on the toilet bowl.
The size is made larger than the dimension a so that the toilet seat 18 receives the load of the spring 31 slightly before the landing on the toilet bowl. With this configuration, when the toilet seat 18 is tilted from a leaning state, even if the user tilts it without holding his / her hand, the rotation of the toilet seat 18 is braked immediately before landing on the toilet bowl to absorb the impact force. Comes out. As a result, not only can the annoying impact sound of the toilet seat 18 hitting the toilet bowl be alleviated, but damage to the toilet seat 18 can also be prevented. This effect can be further enhanced by changing the shape of the cam body so that the brake is gradually applied from the state where the toilet seat 18 is leaned against.

In the present embodiment, the cam body 27 and the spring 31 are capable of performing both the self-supporting action of the toilet seat and the impact absorbing action when the toilet seat is tilted, but it is a configuration that performs either one of them. Also, it is possible to obtain an effect that has never been obtained. Further, although the example of the spring is shown as the spring body, the spring body may be an elastic body having elasticity such as rubber.

Further, even if the toilet lid is provided with a similar mechanism, the toilet lid can perform self-supporting and shock absorption. As described above, according to the present embodiment, even if assembly variation occurs or the frequency of raising and lowering the toilet seat increases, the toilet seat can be reliably made to stand on its own when leaning against the seat.

(EN) Provided is a toilet device which has a good appearance and is not affected by cleaning chemicals and which is provided with toilet seat rotation control means.

Even if the toilet seat is tilted, the impact sound that hits the toilet bowl can be mitigated, and the toilet seat can be prevented from being damaged by the impact.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) It is possible to provide a toilet device having a toilet seat rotation control unit that surely makes the toilet seat self-supporting when the toilet seat is leaned against, even if there are variations in assembly or the frequency of raising and lowering the toilet seat increases.

(2) It is possible to provide a toilet device that looks good and is not corroded or damaged due to cleaning or the like used for cleaning.

(3) Since the spring body is surrounded and supported by the rib provided on the chassis of the support body, the assemblability is good and the durability is high.
